This homeowner in Freedom, NH reached out to our Erickson team with concerns regarding the settlement of the concrete slab of their detached garage. Upon inspection, our specialist helped them determine the entire structure was at risk of settlement, more than just the slab itself. To address the issue with a permanent solution, our team designed and proposed a system utilizing both push piers for supporting the foundation footings, as well as PolyLevel to lift and level the concrete slab on the interior.
To complete the repairs, the project took 4 days to complete, beginning with the installation of the piers. With the structure slightly lifted and stabilized, PolyLevel was the final phase of the project. Tiny port holes were drilled through the surface of the slab in the garage, of which the expanding polymer foam was injected to fill the voids beneath the concrete. As the voids filled, the concrete successfully lifted up and became permanently stabilized. The port holes were then filled and sealed, leaving no signs of repairs on the inside. By not having to tear out and replace all the concrete within the garage, the homeowners saved time and money, and received the results they desired. With their detached garage foundation repaired and protected, they have one less thing to worry about.

Garage Settlement Concerns
The foundation of the garage had settled and shifted, leaving the homeowner very concerned. Our team stabilized the footings with piers to prevent further settlement issues.
Slab Jacking
Our team used slab jacks to assist with lifting the garage slab up slightly to ensure no soils were holding the concrete down as PolyLevel was injected. This allows them to control their lifting procedure much more and helps avoid unwanted additional cracks in the surface of the slab. The crack in this photo was existing due to the structure settling.
Signs of Foundation Settlement
When the garage slab was installed, it was designed to have a slight pitch for drainage. However, over the years settlement of the soils underneath caused the structure and slab to sink. Over just a 4-foot distance on the slab, the concrete was down 2 inches. Over the span of the entire garage, it was much more than that.
